Our Mission
The web is full of tools that ask for sign-ups, charge subscriptions, or secretly ship your data to a server. We believe most day-to-day utility tasks — counting words, calculating duties, generating passwords, converting units — can be done entirely client-side, instantly, for free.
UserToolbox exists to prove that point, one tool at a time.
What We Build
Our tools span several categories:
- Developer utilities — text diff, code screenshots, JSON formatter, regex tester, QR generator
- Content creator tools — word counter, Markdown-to-slides, AI text purifier, Pomodoro timer
- Global trade & commerce — HS code & tariff lookup, CBM / volumetric weight calculator, landed cost estimator, proforma invoice generator, live currency converter
- Everyday calculators — age, percentage, unit converter, password generator
- File & image tools — PDF toolkit, background remover, image editor
Privacy by Design
Every tool on UserToolbox is engineered so that your data never leaves the browser. File processing happens in-memory using the Web APIs your device already has. We collect only anonymous, aggregated page-view analytics (Google Analytics) to understand which tools are most useful. We never sell data, and we never will.
Read our full Privacy Policy for details.
How We're Funded
UserToolbox is free to use and always will be. We sustain the project through non-intrusive display advertising. We do not sell user data, affiliate commissions are never hidden, and sponsored content is always clearly labelled.
